Sentences can be declarative (statements), interrogative (questions) or imperative (orders).
Lily is practising her guitar. (active)
Is Lily practising her guitar? (interrogative)
Go and practise your guitar! (imperative)
To convert one type of sentence into another, we need to make changes to the verb and alter the word order. Interrogative sentences always end with a question mark, and imperative sentences often (but not always) end with an exclamation mark.
In this worksheet you can practise identifying declarative, interrogative and imperative sentences and changing one type of sentence into another.
